Preparation for the next exhibition in the Design for the Other 90% program series brought me to numerous informal communities in mega-cities throughout Southeast Asia. As the world becomes more urban – over half the world now lives in cities – there is much to learn from locations that have been dealing with dense living conditions. In Bangladesh, there are 10 people for every 10.8 square feet of land (approximately 1 person per square foot) making it the second densest country in the world. Only the nation-state of Singapore is denser, with 63 people for every 10.8 square feet of land (roughly 6 people per square foot).
